OK great… I watched the rest of the video since and JL recommends increasing the size of the hands and fingers but doesn’t really explain the method of pinning and locking I’ve got from you in this thread. Unfortunately in Blender 4.0 pack this now wastes a load of space (top). I installed the free UVPacker and it didn’t move the pinned items AND did a much better job (bottom). As far as I can tell you set the padding to 8 for a 4k texture with UV Packer

I will update the title of this thread so it helps others at this stage.
